would kill you so that no other race would have been killed in that manner. After

was filled with oppression and rebellion. The inhabitants of the heavens and earth will
be pleased with him. He will distribute wealth with 'Sihaah'. A Sahaabi asked, 'What is

(Caliphate) three persons will fight but none will overcome it, then black flags
will rise from the east, they will massacre you {Halaku Khan's Army killed 1.6 million
Muslims in Baghdad alone} in such a way that no group has done it ever before. After this
Khalifatullah Mehdi will arrive, when you hear about Mehdi reach him and pledge
allegiance to him even if you have to crawl over snow because he is Caliph of Allah
the Mehdi" (Ibne Maja, Ahmed bin Hanbal, Haakim, Delami, Ruyani, and Nayeem bin Hammad)

battle of Hind (Ghazwa-e-Hind). If I get this battle I will sacrifice my life and belongings. If I am killed
in this battle, I shall be counted among high-ranked martyrs (Afzal Shuhada). If I return as a "Ghazi" (Conqueror),
I will be that Abu Hurrairah who has been freed from the fire of hell." (Sunan Nasai) (Battle related to
Khalifatullah will be called Gazwa in the religious terminology)

Abu HurairaRZ said: When we were sitting with the ProphetSLM Sura Al Jumu'ah came down. Then
when the words "and others of them who have not yet joined them" (Al-Jumu'ah 62:3) came down, the people asked
God's MessengerSLM who they were. Salman Al-FarsiRZ was among us, and placing his hand on
SalmanRZ{Non-Arab, Ajami} the ProphetSLM said "If faith were in the Pleiades (Ath-Thuraiya,
the highest star) some of these men {Non-Arabs, Ajami} would attain it." (Bukhari)

8.
Abu HurayrahRZ: Allah's MessengerSLM recited this verse, "If you turn back He will
substitute other people for you and they will not be like you" (Surah Muhammad, 47:38). The people asked, "Messenger of AllahSLM,
who are these people whom Allah has mentioned will be substituted for us if we turn back and will not be like us?"
He struck Salman al-Farisi {Non-Arab, Ajami} on the thigh and said, "This man {Non-Arab, Ajami} and his people
{Non-Arabs, Ajami}. This man {Non-Arab, Ajami} and his people {Non-Arabs, Ajami} (said two times) If the religion
were in the Pleiades (Ath-Thuraiya, the highest star) men from among the Persians would attain it."
(Tirmidhi, Mishkaat)

9.
Abu HurayrahRZ: When the foreigners {Non-Arabs, Ajami} were mentioned in the presence of Allah's
MessengerSLM He said, 'I have more trust in them (or, in some of them) than I have in you (or, in some
of you).' (Tirmidhi, Mishkaat)

Umme SalmaRZ narrates The ProphetSLM said: "... a man [Hazrat MahdiAS] of the
people of Madina {a large city not Madina Tun-Nabi or Madina Tur-Rasool} {Village Kar'ah became Jaunpur City in 800H}
will come forth to Mecca... (Abu Dawud, Ahmed bin Hanbal, Hakim, Ibn Abi Shebah)

Madina in Qur'an: And from the remote part of the city there came a man running, he said: O my
people! follow the messengers (Surah Yasin, 36:20)

All the ten aforementioned ahadith under the title "MahdiAS's advent in India, Ajam" came true on Hazrat Syed Muhammad Ajami, Hindi, Jaunpuri Mahdi-e-MaudAS, Aamanna wo Sadaqna

Narrated Ibn UmarRZ: Allah's Apostle (SAS) said, "Your period (i.e. the Muslims' period) in comparison to the periods of the previous nations, is like the period between the 'Asr prayer and sunset. (Bukhari) {7000 years/5 Prayers = 1400 Solar 14x3=42=1442 Lunar Years. And they stayed in their Cave three hundred (solar) years, and add nine (for lunar years) (18:25). 5600+1400=7000}

Prophet (SAS) said: The life of my community will not extend much past 1500 Years. (Ahmad Ibn Hanbal, Jalal Uddin Suyuti - Al-Kashf - Al-Hawi)

Narrated Abu HurayrahRZ: The Prophet (SAS) said: Allah will raise for this community at the end of every hundred years the one who will renovate its religion for it. (Sunan Abu-Dawud)

Narrated Abu HurayrahRZ: From Prophet (SAS) the things, which I know that is that The Prophet (SAS) said: Allah will raise for this community at the end of every hundred years the one who will renovate its religion for it and the tenth {901-910} century renovator will be Mahdi. (Jalal Uddin Suyuti - Mirqat Al Saud)

Narrated Abu Tha'labah al-KhushaniRZ: The Prophet (blessings and peace be upon him) said: Allah will not fail to detain this community for less than half a day (500 Years). {Rasool Allah's SAS expectation} (Abu Dawud)

Narrated Sa'd ibn Abu WaqqasRZ: The Prophet (SAS) said: I hope {Dua} my community will not fail to maintain their position in the sight of their Lord if He delays them half a day. Sa'd was asked: How long is half a day? He said: It is five hundred years (500 Years). {Rasool Allah's SAS Dua} (Abu Dawud)

Narrated Abdullah ibn Mas'udRZ: The Prophet (SAS) said: If only one day {1000 Years} of this world remained. Allah would lengthen that day, till He raised up in it a man (Al Mahdi) who belongs to me or to my family, whose father's name is the same as my father's and whose name will be the same as mine. (Abu Dawud)

For sure Prophet (SAS) does not stay in his grave for One Thousand (1000) Years. (Jalal Uddin Suyuti - AlKashf)

Narrated by Mohammed bin HanafiyyaRZ: We were sitting with Hazrat Ali RZ, One person questioned him about Mahdi, he said it is far and he made nine {900} with his hand and said he will appear at the end of times. (Nayeem bin Hammad, Al Salami - Iqdud Durar Fi Alamat Al Mahdi Al Muntazar)

Hazrath AnasRZ narrates the ProphetSLM is narrated to have said, whoever of you finds Esa Bin MaryanAS convey my Salaam to him. (Haakim)

The ProphetSLM is narrated to have said, what will be your state of affairs, when EsaAS will descend among you, and lead you in prayers. (Muslim)

Hazrath Abu Sayeed KhudriRZ narrates the ProphetSLM is narrated to have said, When Bai'ah is given for two Khalifa's, slay the last one who takes the Bai'ah (because his Khilafat is batil with the presence of the first Khalifa). (Muslim)

Hazrath Syedna Huzaifa Asad GhifariRZ narrates, while we were discussing the ProphetSLM came to us and asked, what you were discussing? We replied, we were talking about Qayamah. He said Qayamah will not be established until 10 signs are not seen before it, then he narrated about smoke, Dajjal, the animals on earth, the rising of the sun from West, the descending of EsaAS, the coming of Gog and Magog, the sinking of earth at 3 places i.e. the penetration of earth, one in East, another in West and the third one in the Arabian Peninsula, and after all these signs a fire will be born it will start from Yemen herding the people and take them towards Mahshar (Mahshar is the land in Syria). (Muslim)

Hazrath Nawas Bin SammanRZ narrates, one morning the ProphetSLM narrated about Dajjal, sometime he shortened it and sometimes he lengthened (i.e. sometimes he cut short and sometimes he said this fitna is a big one, sometimes he spoke in low voice, sometimes his voice was raised) until we thought the Dajjal might be hiding in between the group of date trees. In the evening when we went to see the ProphetSLM he enquired about (the fear on) our faces. He asked, how are you, we replied O! ProphetSLM you have mentioned about Dajjal and sometimes you shortened and sometimes went into the details, we thought Dajjal might be hiding in between the group of date trees (i.e. his coming is near). The ProphetSLM replied, apart from Dajjal I fear from many other things on you (regarding the trials and infightings). If I am alive and Dajjal appears then I will face him first (I will fight him) and save you from his mischief. If he appears and I am no more in between you, every Muslim Man should face him and Allah will be Khalifa and defender on every Muslim Man. But Dajjal is young with curly hairs, his eyes are protruded similar to Abdul Uzza Bin Qattan. Whoever of you finds Dajjal should recite the opening verses of Surah Kahf over him. Definitely, he will appear the route in between Syria and Iraq spreading evil on his left and right side. O! Servants of Allah, stay firm on faith, the companions asked, O! MessengerSLM of AllahSWT how long will he be on Earth? For 40 days, he replied. Each day will be equal to a year, each day will be equal to a month, each day will be equal to a week, and the remaining days would be similar to yours (i.e. as per our days Dajjal will exist for 1 year, 2 months and 14 days). The companions asked, O! ProphetSLM the day that is equal to a year, on this day we would be suffice with only one day of prayers? He said, No! On this day (the prayers of the year) (Now clocks are available and time can easily be measured). Imam NowawiRA says, if the ProphetSLM would not clearly said about this, it was thought that offering of only 5 prayers was sufficient on this day, because in each day and night how long it might be, Allah has made only 5 prayers obligatory, but this thought was nullified on the basis of nus i.e. as per Qur'anic injunction. The translator says, on the planet Earth on the 9th degree from the equator where the sunrise is similar to morning, this place has 6 months day and 6 months night. So a complete day and night equals to a whole year. For example if a man reaches to that place and survives, he has to offer only 5 prayers in a whole year. The companions asked, O! ProphetSLM how he will walk on earth? He replied, like this cloud, which is driven by wind from behind. He would come to a Qaum community and would invite them, they will bring faith on him and would follow him, he will direct the skies and it will start raining and on his command the earth will bring forth grass and grains. On dusk when their cattle returns their horns will be longer than before, udders would be spread (with milk) and their bellies would be arched (i.e. too fat). Then Dajjal will visit another Qaum community, he will invite them also but they will not accept his words, he will move away from them, draught and starvation will befall upon them. Their hands would be empty nothing of their wealth would be left with them. When Dajjal walks on barren land he will say, O earth! Bring forth your treasures, the treasure would appear and gather around him similar to honey Bees, which gather around the Queen Bee. Then he will call a young man and would cut him into 2 pieces with a single strike of sword with perfect aim. Then he will bring him back to life and would call him, with this the boy will come jumping with a smiling face. Dajjal would be in this condition and suddenly Allah will send down Hazrath EsaAS. EsaAS would descend in the city of Damascus at the eastern side near the white minaret, he would be draped in yellow dress. Both his hands would be resting the shoulders of two angels, when EsaAS bends his head sweat will drip, when he lifts his head the drops will fall like pearls, wherever the fragrance of EsaAS reaches the infidels would die. His fragrance would reach till the extent of his sight, and then he would start searching for Dajjal until he finds him at Bab-e-Ludd (this mount is situated in Syria) and he would kill Dajjal. Then those people will come out towards EsaAS whom Allah had saved them from the trials of Dajjal. Then he will soothe their faces with his palms and will give them glad tidings of their high stations, which were kept for them in Paradise. He will be in this condition, Allah will send inspiration to him saying, "I have brought out my servants, nobody has the strength to fight with them, and you take them towards the mount of Tur for refuge", and Allah will send Gog and Magog and they will come out from all peaks. Before them people will cross over the river of Tibristan and would drink all of its water making it dry, from among them those who came after would say, there used to be water in it. They would continue to walk until they reach a mountaineous region filled with trees i.e. the mountaineous region of Bait-ul-Muqaddis and would say, we have killed the inhabitants of earth and now come we will kill the inhabitants in the skies and they will start shooting arrows in the sky, but Allah would fill their arrow with blood and return them back, they will think the inhabitants of the skies are also killed (this article is not from this narration but was taken from the forth coming narration). EsaAS the Prophet of Allah and his companions would be locked inside, their condition would be, the head of a bull with them would be better than your 100 gold coins (i.e. food would be scarce). EsaAS and his companions would supplicate. Allah will send a torment on the people of Gog and Magog in the shape of a worm, which would take birth in their necks, and until morning they will all die similar to the death of a man. Then EsaAS along with his companions would step on the ground, they will not find space even the size of a palm, from their stink and carcass (i.e. their stinking corpses would be spread across the earth), then EsaAS and his companions would supplicate and Allah will send flocks of birds with their necks similar of camel necks, they would carry the dead bodies and throw them where they have been commanded by Allah, on that day Allah will send showers of rains and then the earth would be commanded to gather all its fruits and return back to its blessings, on this day a single pomegranate would be consumed by a whole groh community and from its peelings a house similar to a bungalow would be built and people would take rest in its shadow and milk will also be blessed, so that milk laden she-camel would be sufficient to quench the thirst of a big whole group. Milk laden Cow would be sufficient for a big group. Milk laden Goat would be sufficient for a big family. People would be in this condition then Allah would send fresh and pure soothing breeze which will pass through their armpits and with its effect the souls of each and every Momin and Muslim would be extracted, the wicked and the evil ones would be left out, they would copulate with women openly similar to donkeys and the Qayamah will be established on them. (Muslim)

It is narrated by Ibn Manada that Ka’ab Ahbar has said that there would be twelve Mahdis and after that Esa Roohullah AS would descend and kill Dajjal [Anti-Christ].
